Itchy labia major/outer labia

Georgia

Okay so right next to the hood of my clit, the very upper part of my labia is so itchy. My skin is ridulously dry all over my body rn, so I think that's part of it. Also my hair is grown out a bit because I haven't had time to shave recently. I've been itching it because it's hard to not and now that upper part of my labia is red. I just got done having a yeast infection so I'm afraid to put lotion down there because they say to keep your vaginal area dry in order to avoid yeast infections. I had told my lady doctor about these and she had said they are most likely from sweat and clothing rubbing. There's no sores, it's only painful because I'm itching it. This is awful and it's stressing me, anyone have any tips?
